Worst case burstiness increase due to FIFO multiplexing

Jean-Yves Le Boudec, Juan Echagüe

We consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem arises in scenarios where aggregate multiplexing is performed, such as differe ...

Analytic Assessment of Telephone Transmission Impact on ASR Performance Using a Simulation Model

Hervé Bourlard

This paper addresses the impact of telephone transmission channels on automatic speech recognition (ASR) performance. A real-time simulation model is described and implemented, which allows impairments that are encountered in traditional as well as modern ...

Broadcast quality video over IP

We consider the problem of designing systems for the transmission of high-quality video signals over certain high-speed segments of the public IP network. Our most important contribution is the definition of a network/coder interface for IP networks which ...

High-bandwidth internet video telephony

Martin Vetterli

We consider the problem of full-duplex video transmission over the Internet, under real-time delay constraints. In this work we present the design of a complete communications system, whose salient features are: (a) a soft real-time transport protocol, who ...

Integration of Internet and Telecommunications- An Architecture for Hybrid Services

Jean-Pierre Hubaux

In this article, we propose an architecture for hybrid services, i.e., services that span many network technologies, such as the Public Switched Telephone Network (PSTN), cellular networks and networks based on the Internet Protocol (IP). These services wi ...

Voice Service Interworking for PSTN and IP Networks

Jean-Pierre Hubaux

n recent years, the Internet has proven its ability to carry real-time data, including voice. Today, a small amount of voice traffic has already been diverted from the Public Switched Telephone Network (PSTN) to the Internet. If it expands, this phenomenon ...

Circuit Emulation over IP Networks

Jean-Pierre Hubaux

The best-effort service offered by the Internet is not suitable for a large variety of multimedia applications, which require strict guarantees on losses and end-to-end delay. We design functionalities and mechanisms for RTP in order to provide a transport ...

Circuit Emulation over IP Networks

Jean-Pierre Hubaux

Recent developments in transmission and switching technology has made available low-cost gigabit network capacity forpacket-based WANs (e.g., IP over WDM), that will not require the intermediate SONET/SDH multiplexing layer. For competitive operators that ...
